STENOGRAPHIC TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented lilay 26, 1914.

Application filed March 11, 1913. Serial No. 753,632.

To all whom it may concern Be it known that I WARD S. IRELAND, aresident of Owensboro, in the county of Daviess and State of Kentucky,have invented certain new and useful Improvements in StenographicType-Writing Machines; and I do hereby declare the following to beafull, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to improvements in type-writing machines andparticularly to stenographic writing machines, the object of theinvention being to provide means whereby the various operatingmechanisms, including the, key and type lever mechanism, thepaper-feeding mechanism and the inking ribbon -mechanism, may have theirstrokes adjusted simultaneously andto so construct and arrange suchadjusting means that it shall be readily accessible,- easy tomanipulate, and accurate in operation.

With this object in view the invention consists in certain novelfeatures'ot con:

struction and combination of parts as hereinafter set forth and pointedout in the claims.

In the accompanying drawings; Figure 1 is a longitudinal sectional viewof a stenographic writing machine embodying my improvements; Fig. 2 is arear elevation showing the adjusting device, and Fig. 3 is an enlargedside elevation, partly in section showing the adjusting device and itsapplication.

1 represents the frame of a type-writing machine, provided at its rearend with a door.2 on which a bracket 3 is located and adapted to supporta supply roll 4 of paper. A platen 5 is located over the upperportion ofthe frame 1 and in the lower portion of said frame a key lever bearing 6is secured A plurality of key levers 7 (each provided at its inner orrear end with a suitable key or button 8) have pivotal bearings in themounting 6 and each of said key levers is provided with an upwardlyprojecting arm 9 having a loose pivotal connection at its upper end withthe lower arm of a type lever 10, the upper arm of said type lever beingprovided with a type normally disfront of the platen. Thus it isapparent that when a key is depressed, motion will be imparted throughthe key lever to the type lever and cause the type on the upper end ofthe latter to movetoward the platen, it being of course understoodthatan inking ribbon and a paper strip will be disposed between said typeand platen as will be more fully hereinafter set forth.

The paper strip will be fed from the roll 4 past the platen and will beguided in its movements by guides such as illustrated at 11, 12, and 13,the paper passing from the guide 13 rearwardly through a paper-feedmechanism 14. This paper-feed'mechanism includes levers 15 to the lowerends of which links 16 are pivotally connected. These links projectforwardly and are connected at their forward ends to rearwardlyprojecting arms 17. The arms 17 project rearwardly from the lower endsof links 18 pivot-ally suspended from a fixed part of the .mechanism.The suspended links 18 serve to support a universal bar 19, the ends ofwhich latter are secured to said links and the said universal bar isdisposed in front of the type levers in proximity to the pivotalconnection of the latter with the key lever arms 9.

I Inkingribbon spools, such as illustrated at 20, are provided and theinking ribbon passes from one of these spools to the other and betweenthe type and the paper strip, as will be readily understood. Ratchetmechanism 21 is provided for actuating the ribbon spools and isconnected with the latter through the medium of suitable gearing.,Theactuating dogs 22 of this ratchet mechanismare carried by theuniversal bar 19.

The type on the type levers are maintained in'and returned to theirnormal positions away'from the inking ribbon by means of springs 23, oneend of each of which is attached to the frame and the other end to thelower arm of a type lever.

When a key lever is depressed for actuating a type lever as aboveexplained, the universal bar will be moved in a direction toward thefront of the machine. In thus moving the universal bar, motion istransmitted through the arms 17 links 16 and levers 15 to the paper-feedmechanism and motion will also be transmitted by such forward movementof the universal bar to the dogs 23 of the ratchet mechanism, thusactuating said ratchet mechanism to impart motion for feeding theribbon. If movement of the arms 9 in a direction toward the rear of themachine be limited, the strokes of the type levers, the paper-teedmechanism and the ribbon feed mechanism will also be limited. llt isvaluable and important to be able to accurately and synchronously adjustthe strokes of these parts of the mechanism and for this vices now to beexplained are employed.

A yoke 24 is disposed behind the arms 9 of the key levers and carries inits horizontal portion, apad 25 to be engaged by said arms. The lowerportions of the depending arms 26 of the yoke 24 are disposed behind abar 27 fixed in the frame-work 1. This bar is provided with partlyspherical projections 28 andthe adjacent arms of yoke 24 are made withsimilarly shaped sockets 29 to receive said spherical projections, thus.rocking adjustment of.

permitting a slight the yoke 24. To effect such adjustment and to retainthe yoke in the position in which it may be adjusted, Screws 30 arepassed freely through holes 31 in the yoke arms above and below themounting of said arms on the bar 27 and these screws enter threadedholes or sockets 31 in the bar 27. It is apparent that by unscrewing oneof the screws and screwing the other screw in each yoke arm, the yokewill be rocked on its bearing and the pad 25 carried by the horizontalportion of said yoke will be adjusted either in a direction toward oraway from the key lever arms 9. The pad 25 carried by the yoke 24constitutes a stop which limits the forward movement of the key leverarms and hence limits the backward movement of the upper arms of thetype le-' vers and regulates the normal space'between the type and theplaten. Should it be desired to shorten the stroke of the type levers,the yoke 24 will be adjusted, by

means of the screws. 30,.in such'manner as to move the pad 25 in adirection toward the key lever arms 9 and to lengthen the stroke theyoke will be adjusted in the reverse direction. v

In view of the fact that the operation of the key and type levermechanism actuates the universal bar 19 and that both the paper-feedingmechanism and the ribbont'eeding mechanism are actuated by the movementsof said universal bar, it will be seen that the adjustments of the yoke24: as above described will not only. adjust the stroke of the typelevers, but will also adjust synchronously the strokes of the paper-feedand ribbon-teed meohanisms,--so that l purpose the de noeaiia adjustedsimultaneously and in synchronism with each other.

Having fully describedmy invention, what I claim as new and desire tosecure by Let ters-Patent, is;

1. in a type-writin machine, the combination with key an typemechanisms, at platen and paper feed mechanism, of means actuated by thekey and type lever mechanism for actuating the paper-feed mechanism andmeans adjustable relatively to said mechanisms for adjusting the strokesof all of said mechanisms simultaneously.

2. In a type-writing machine, the combination with key and type levermechanism, a platen,; aper-feed mechanism, and ribhon-feed: echanism, ofmeans operatively connecting said mechanisms, and adjusting meansassociated with one of said mechanisms and operative to adjust thestrokes of all of said mechanisms simultaneously.

3. In a type-writing machine, the combination with key levers havingarms, type levers operatively connected with said arms, and a platen,ofa yoke adjacent to and having a part constituting a stop for the keylever arm, and means for effecting a rocking adjustment of said yoke tomove the part thereof which constitutes a stop uniformly with respect toall of said key lever arms and thereby vary the stroke of the key leversand the type levers'and for securing said yokein'its adjusted position.

4. In a type-writing machine, the combination with writing means,paper-feeding means, and ribbon-feeding means operatively connected witheach other, of a fixed bar and a yoke mounted to be rocked on said barand constituting a stop associated with one of said mechanisms and meansaboveand below the mountings of said yoke on the fixed bar for adjustingthe yoke in two directions to-adjust the strokes of all of saidmechanisms simultaneously.

7 5. lln a type-writing machine, the combination with key and type levermechanism,

a platen, paper feed mechanism and ribbon feed mechanism of meansoperatively connecting said mechanisms. and means for adj usting thestrokes of said mechanisms synchronously.

In testimony whereof, I have signed this specification in the presenceof two sub.- scribing witnesses.
